wp.newPost no longer posting "older date"

Hello all.

A friend and I are trying to figure out a solution or possible source of a problem we are experiencing.

We have a spreadsheet which we use to pull information from, in order to create “new posts” in WordPress (that’s the short end of it).

The script which does the processing of the information from the spreadsheet into WordPress uses Python. From the python script (specifically using “pyblog”), we use XML-RPC to connect and create new posts.

So, here is the problem. Recently, we have noticed that new posts work properly except for the data of the post being created shows the current time we connect up and post i.e. today’s date for example.

The problem is that we have successfully been creating “new posts” with a timestamp/date of the original time the article/posts we are importing was created. If an article was created on Feb. 10, 2010 then we have been able to reflect that in the post. However, that is not working now.

We have disabled all plugins and cannot seem to figure out what has changed. The only thing we know for sure is that everything was working with the dates until WP 3.8.1.

Has anyone else seen a similar problem with wp.newPost and the dates not showing up properly if set to something different than the time of post since updating to 3.8.1?

Is the only possibility to roll back the DB to 3.8.0? We have done a lot of updating since 3.8.0 and that would erase a lot of work.

Thoughts?

.. and thanks!
